ABSTRACT:
Geothermal energy is recovered by (1) introducing into a subterranean heat exchange medium which is in heat exchange with a high temperature formation a liquified vapor which will vaporize at the conditions of the medium; (2) vaporizing the liquified vapor; (3) confining the liquified vapor until pressurized; and (4) recovering pressurized vapor having thermal and pressure-volume energy converted from the high temperature formation.
